We look at the division of 17440089 by 248 
The aim is to understand the frequency of 248 in 17440089.

Advancing to step 1:
When dividing 1 by 248, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 248

Advancing to step 2:
If we divide 17 by 248, we get 0 and a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 248

On to step 3:
When dividing 174 by 248, we get 0 with a remainder of 174.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 174 leaves us with 174.
Take the next digit (4) from the dividend and append it to 174, then repeat: 1744 / 248

Advancing to step 4:
248 goes into 1744 7 times with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 1736 from 1744 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 248

Going ahead to step 5:
248 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 70.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (0) of the dividend behind the 80 and repeat the process: 800 / 248

On to step 6:
The number 248 fits into 800 3 times, leaving a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 703.0
Subtract 744 from 800 to get 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 248

Step 7:
When dividing 568 by 248, we get 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 7032.0
Subtract 496 from 568 to get 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 248

Moving on to step 8:
729 divided by 248 is 2 with a remainder of 233.
The number 2 becomes the next digit in our result. 
Result so far: 70322.0
Subtracting 496 from 729 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 9:
When dividing 2330 by 248, we get 9 with a remainder of 98.
The next digit of our result is 9. 
Result so far: 70322.9
Subtract 2232 from 2330 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 10:
980 divided by 248 is 3 with a remainder of 236.
Put 3 as the next digit of the answer. 
Result so far: 70322.93
If we take 744 away from 980, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 11:
248 can be fit into 2360 9 times, resulting in a remainder of 128.
The next digit of our result is 9. 
Result so far: 70322.939
If we take 2232 away from 2360, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
248 can be fit into 1280 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 70322.9395
Subtract 1240 from 1280 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
400 divided by 248 is 1 with a remainder of 152.
Use 1 as the next digit of our solution. 
Result so far: 70322.93951
If we take 248 away from 400, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 14:
1520 divided by 248 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 70322.939516
The remainder is 32 after subtracting 1488 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
248 can be fit into 320 1 times, resulting in a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 70322.9395161
The remainder is 72 after subtracting 248 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 16:
When dividing 720 by 248, we get 2 with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 70322.93951612
Subtract 496 from 720 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Our division results in 70322.93951612 with a remaining 2.24e-07.
